Abstract

L'invention concerne un palier radial bidirectionnel conçu pour supporter rotatif un rotor ou un arbre. Ledit palier peut comporter une bague (12) dont l'alésage intérieur est doté d'éléments de retenue anti-rotation (22) pouvant être espacés régulièrement et s'étendant sur la longueur radiale de celui-ci. L'alésage intérieur de la bague peut se présenter sous forme de multiples lobes (25). L'interface des lobes adjacents, une feuille souple (14) et un sous-ressort en feuille (16) forment des cales convergentes. La combinaison de l'alésage à lobes, de la feuille souple et du sous-ressort permet la formation de cales convergentes symétriques entourant l'arbre ou le rotor. Selon un autre aspect de l'invention, une seule feuille souple peut être combinée avec l'alésage à lobes et un ou plusieurs sous-ressorts en feuille, de manière qu'au moins deux cales convergentes symétriques soient formées.
